<p>A&nbsp; <a href="../h_definition.htm#damapspin">DAMAPSPIN</a>&nbsp; DS 
contains a regular <a href="../h_definition.htm#damap">DAMAP</a> DS%M and a
<a href="../h_definition.htm#spinmatrix">SPINMATRIX</a> DS%S.</p>

<p>&nbsp;</p>

<p>The <a href="../h_definition.htm#spinmatrix">SPINMATRIX</a> is itself a 3 by 3 
array of polymorphs (<a href="../h_definition.htm#real_8">REAL_8</a>)&nbsp; 
DS%S%S(3,3) which represents the rotation for the spin.</p>

<p>In general, in an accelerator, the spin matrix DS%S%S(3,3) with be a function 
of all the parameters of the Taylor map including the phase coordinates.</p>

<p> <a href="../h_definition.htm#damapspin">DAMAPSPIN</a> can be concatenated:</p>
